Last night, Yu Ming had challenged him, and sure enough, Wu Jingguo accepted the challenge saying that he was ready to head to North Peak at any time to get more information about what was going on in that place.
Sure enough, not only was Yu Ming curious about the new Demon King, but Wu Jingguo also had the same curiosity. That was why Wu Jingguo didn't hesitate to follow Yu Ming to leave the South Slum today so that they could get answers to their questions.
"Aiyah! You two just came to join us yesterday, but now you're already about to leave us? Why are you in such a hurry? Is it because the food here isn't that good? Or maybe it's because of the bugs that keep bothering you?" Bolin asked the two young men as they were both about to leave the South Slum just a day after they arrived at that place.
